In this process, the ilmenite is first heated in air above 900°C to oxidise the Fe 2+ in the ilmenite to Fe 3+ forming micro-cracks in the ilmenite grains. The oxidised product is then reduced at 800–850°C in a H 2 –CO–CO 2 –H 2 O gas mixture under conditions that minimise the formation of metallic iron.
